If you did this with the intent to die, wouldn't it really be suicide? I doubt that if there is a Heaven, you'd be able to fool yourself in. God's supposed to be a bit smarter and more omniscient than your average Joe.

Oh? No, 6th commandment is to not murder. Noah was told to kill murderers. Saul and David were warriors, and commanded to wipe out the Philistines, Moses killed a slave driver in Egypt, the Hebrews were in war like crazy, and wiped Jericho off the map except for a hooker and her family. Killing isn't wrong, it's murder that's wrong. That's the one that has their blood crying out from the ground for justice.
